Solve the following systems by graphing
You can't solve anything with these, they are the same equations
:
3x - 6y = 9
Simplify by dividing equation by 3:
x - 2y = 3
:
:
To plot the graph put it in the general "y =" form
x - 2y = 3
-2y = 3 - x
Mult eq by -1 to get a positive y
+2y = x - 3
y = .5x - 1.5
:
Plot from x = -2 to x = + 3
:
It should look like this:
